Homework Statement
Grounded conducting sphere in uniform electric field has potential
V(r,θ) = -Vo(1 - (R/r)3)*cosθ
Find Er and Eθ.
Homework Equations
The Attempt at a Solution
In the textbook I found
Er = -∂V/∂r
Eθ = -1/r ∂V/∂θ
Those are in the chapter we're working with but those two equations are in the section talking about the electric field of dipoles. Do those equations apply for the problem I'm working on?
